uninstall committed patch

[V. V. Ravi Kumar_1]

hi all,

i want to install PHKL_16433 on hp-ux 11.00 machine. but a superceded patch PHKL_20333 is already installed on the machine. when i try to uninstall PHKL_20333, it is saying this patch is committed and can not uninstalled. is there any way to uninstall committed patch.

i was suggested to install PHKL_16433 to test the performance of one of our application.

thanks in advance
ravi

I don't think you can. Surely the newer patch is better to have.
Why do you need to install the older patch.

Hi,

As far as I know it's not possible to remove a committed patch !

Hi Ravi,

Appears someone has ran the cleanup script - which removes the files needed to remove the patch.
Must have needed the /var/adm/sw/save space at some time in the past.
Think you're out of luck.

I always run a backup of /var/adm/sw/save before and after a cleanup. I you cannot recover this directory there is nothing you can do.

Ravi,

You could try reinstalling the newer patch - you'll have to force the reinstall.
You may be able to remove it then. But as in all uninstalls - watch out for dependencies.

Rgds,
Jeff

Hi Ravi:

The superceded patches are always better and safe. There can be issues in future if you remove them and replace with an older one. However if you really needs to remove the committed patch, then check this document and steps (TKB #UPATCKBRC00007112):

Not sure why you would want to install an older patch that was superseeded. Anyway this is how you can remove a "committed" patch.

SD makes rollback copies of all files and archive library objects modified in var/adm/sw/save. If the patch is "committed" these copies are removed from /var/adm/sw/save. So the only way you can remove "committed" patch is to install from backup ..
1) Restore /var/adm/sw/save/PHKL_20333
2) Run ..
# cleanup -s
===> Modify the patch state so that it will be modified to either "superseded" or "applied".
3) Now swremove it.
